Back in 2014 we installed an inground fibreglass pool and illuminated it with Pentair GloBrites. The vibrant colour from these LEDs highlights the glass resin and creates a magical scene. Unfortunately, the product themselves are prone to a high failure rate. As of 2025, we have gone through 3 sets at over $1500 per set. The first set was covered under warranty, unfortunately the next sets weren’t. I’m also fortunate that I can change the lights myself so we’re able to save on labour but it is still a huge investment for 2 lights.

This spring we unwrapped the pool after its winter slumber and found that another GloBrite has failed. Shocked? No. Disappointed, yes. I researched replacements and have heard relatively good things about the Pentair MicroBrites. I purchased two new MicroBrites as well as the corresponding adapters to fit MicroBrites in to a GloBrite housing. The parts are: “Pentair Adapter Microbrite To Globrite – 618040” and “Pentair EC-620425 MicroBrite Color LED Light 100′”.

For anyone worried if there’s a noticeable difference if you mix-and-match the GloBrites with the MicroBrites, there isn’t. Physically the lights are smaller and the power cable is thinner, but the output matches the GloBrites. I took this picture to show the similarities between the two when using a fixed colour. I did not run a colour-swim.
